Schematic in PDF form, 3.44 MB, for the FH52M board with Compal number LA-J891P, revision 1A, marked as a 0302 release prepared for CSD service use. It documents power rails, the embedded controller, BIOS flash, CPU and GPU supply circuits and connectors, making it valuable for tracing voltages, checking power sequencing and identifying shorted components. The LA-xxxxP code follows Compal ODM numbering. Since a revision 1B board also exists, compare the revision printed on the PCB before relying on part references.
